Eye Precision Mobile

To be used for Research and Education only, not approved for medical use or diagnosis. EyePrecision turns ordinary video into precise, frame-by-frame eye-movement data — right on your iPhone or iPad. Record a close-up clip of an eye with the built-in camera, or load one you already have, and EyePrecision tracks the pupil through every frame, measures how far it moves, and plots the motion as clean horizontal and vertical graphs. Export the raw numbers whenever you need them. Built for researchers, coaches, educators and students who want repeatable eye-movement measurements without a lab full of hardware. WHAT YOU CAN DO Capture sharp eye video with adjustable torch levels, variable zoom, and high-frame-rate recording up to 240 fps. Or import any existing video from Photos or Files. Fine-tune contrast, exposure, and hue so the pupil stands out before tracking. Mark the pupil with a tap — EyePrecision follows it automatically, even through fast movements and blinks. Add an optional head-position marker so head motion is subtracted from the result. Review annotated playback side by side with horizontal and vertical movement graphs. Export results as video and CSV to analyze anywhere. Keep a tidy history of past sessions, rename them, and share in a tap. PAIR WITH EP ANIMATIONS Connect over your local network to trigger and follow on-screen animation targets, keeping your stimulus and your capture in sync. PRECISE BY DESIGN A refined tracking engine locks onto the darkest, roundest region of the eye and re-acquires it after rapid movements, so your measurements stay consistent from frame to frame. EyePrecision is a measurement and analysis tool for research, education, training, and personal insight. It is not a medical device and is not intended to diagnose, treat, cure, or monitor any health condition.
